Short summary
Monitoring systems capable of quantifying rates and distribution of land subsidence and detection of ground rupture for many types of infrastructure including dams, levees, channels, basins, roadways, and mining facilities are discussed. Methods implemented include optical leveling and GPS surveys, ground reconnaissance, photo-geological analysis, groundwater monitoring, tape-extensometers, InSAR, borehole tiltmeters, microseismic arrays, excavation of monitoring trenches, and TDR.
